HENRY A. WISE WOOD, OF NEW YORK, N. Y., ASSIGNOR T WOOD NEVJSPAPEE MACHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA PRESS UNIT DRIVE Application filed February 18, 1926', Serial No. 89,870. Renewed June 2, 1932 This invention relates to the connection of arranged end to end and in alignment and several units of a printing press with the without any gears of any sort or other relanecessary folder or folders. The principal tively movable partsfor transmitting the objects of the invention are to connect the power from one to another. These driving units and folders in such a way as to reduce shafts, as well as the main shaft, are all 55 the expense of manufacture and maintecated at the same level, or substantially so, nance; to avoid back lash in stopping and namely the level of all the printing couples, starting the presses by the elimination of the so vertical shafts are eliminated with their numerous gears now employed; and do away gears.

The principal object of this invention is to Intermediate vertical shafts and gears are avoid these difiiculties and at the same time done away with, except that one pair of gears omit the cost of the gears and of their mainis used, but there is an important saving in tenance. the number of gears required for each ma- I will not describe the details of the press chine.

It will be understood, of course, that the only one form of the invention I am aware press units can be provided with inking of the fact that modifications can be made mechanism, fresh roll supports, etc. therein by any person skilled in the art with I This type ofpress is simplified, as far as out departing from the scope of the invention 40 the drive is concerned, to'as high a degree as expressed in the claim. Therefore I do not as is possible in a multiple unit press. This wish to be limited to all the details of conwill be seen to be true, when it is pointed out struction herein shown and described, but that all the press units and folders are driven, what I do claim is: from a single main shaft on one of them, In aprinting system, the combination with through an unbroken 11116 f driving Shafts a plurality of press units arranged parallel to each other and registering With each other and p a folding mechanism located at the end of the series so that the Whole series is in alignment but the driving shafts of the press units and folder are all parallel, said driving shafts for the press units each being the shaft of one of the cylinders of the printing couple, and the folder having shafts perpendicular to the folder driving shaft for operating it but in the same horizontal plane, of a longitudinal main shaft extending along the system perpendicular to all of said driving shafts and in the same horizontal plane, and means connected withsaid main shaft for driving all the parallel shafts directly.

In testimony whereof I have hereunto affixed my signature.
